Whenever a creature makes a deal with a demon,
the hatethrall acts as an advisor. It serves its new client whom the
greater demons sees as a potential asset. The hatethrall seldom takes
action itself. Instead, this demon
prefers to whisper to its client, suggesting whom to kill or what
territory to overtake. While the creature may see itself as the one in
command, the hatethrall is actually the one with the power. Should the
creature choose to ignore a hatethrall’s suggestion,
the demon
will charm the creature and order it to do its bidding.

Several warlords and would-be dictators in the River
Nations have a hatethrall lurking in the shadows. A few are even aware
that the previous warlord of the land they now rule was advised by the
very same hatethrall. These warlords know that the same could happen to
them on a whim of hatethrall and eagerly strive to keep it pleased. When
a hatethrall is forced to fight, it prefers to use its ray of fire
attack as its main weapon alternated with darkness
and doom
to keep other creatures at bay. If the fight looks bad, it will summon
in another hatethrall or a shadow demons to aid it. When the hatethrall
loses more than half its hit
points it will use either teleport
or planeshift to remove itself from the fight.

A hatethrall is about 1 ft. tall, weights about 10
pounds, and appears like a human skull engulfed in flames.
